The responses to Items 4, 5 and 6 of this Schedule 13D are incorporated into this Item 3 by reference.

The total purchase price for the Common Shares reported herein was approximately R$14.19 billion, or R$25.51 per Common Share.

Additionally, as required by Brazilian law, the Reporting Persons (acting through State Grid Brazil or another affiliate) currently expect to use to the working capital of one or more Reporting Persons or their affiliates other than the Issuer, and, potentially, debt financing arrangements to be entered into by the Reporting Persons or their affiliates other than the Issuer, to consummate (a) a cash tender offer for all of the Common Shares not already owned by State Grid Brazil (the “Tender Offer”) and (b) a cash tender offer for all of the equity securities of the Issuer’s BM&FBOVESPA-listed subsidiary, CPFL Energias Renováveis S.A., not already directly or indirectly owned by the Issuer (the “Subsidiary Tender Offer”).

Item 4.

Purpose of Transaction.

The responses to Items 3, 5 and 6 of this Schedule 13D are incorporated into this Item 4 by reference.

•

On September 2, 2016, State Grid Brazil and SGID entered into a share purchase agreement, dated September 2, 2016 (the “Original SPA”), with Camargo Correa S.A. (“Camargo”) and ESC (which was a wholly-owned subsidiary of Camargo until sold to State Grid Brazil at the Closing), pursuant to which Camargo and ESC agreed to sell to State Grid Brazil all of the Seller Shares (as defined below) owned by them, on and subject to the terms and conditions set forth in the Original SPA.

•

On October 3, 2016, Camargo and ESC exercised their option (the “Indirect Sale Option”) pursuant to the Original SPA to convert the originally proposed direct acquisition by State Grid Brazil of the Seller Shares held by ESC into an indirect acquisition of such Seller Shares by means of the direct acquisition by State Grid Brazil from Camargo and Camargo’s wholly-owned subsidiary, VBC Energia S.A. (“VBC”), of 100% of the equity interests of ESC. Camargo and ESC exercised the Indirect Sale Option by executing and delivering to State Grid Brazil, together with VBC, an Indirect Sale Notice and Accession Agreement (the “Indirect Sale Notice and Accession Agreement”) pursuant to which VBC and Camargo each became a “Seller” pursuant to the Original SPA with respect to the ESC equity interests held by it. Camargo also remained a “Seller” pursuant to the Original SPA with respect to the Seller Shares directly held by it.

•

On October 6, 2016, Caixa de Previdência dos Funcionários do Banco do Brasil – PREVI, a closed complementary pension fund (entidade fechada de previdência complementar) organized under

the laws of the Federative Republic of Brazil (“PREVI”), perfected the exercise of certain tag-along rights available to it pursuant to the Issuer Shareholders Agreement (defined below) in connection with the execution by Camargo and ESC of the Original SPA by executing and delivering to State Grid Brazil a Seller Accession Agreement (the “PREVI Accession Agreement”) pursuant to which PREVI became a party to the Original SPA in the position of a “Seller” and agreed to sell to State Grid Brazil all of the Seller Shares (as defined below) owned by it. The “Issuer Shareholders Agreement” means, for purposes of this Schedule 13D, the Shareholders Agreement of the Issuer, dated March 22, 2002 and amended on August 27, 2002, November 5, 2003 and December 6, 2007, by and among ESC, PREVI and the Bonaire Investor (as defined below).

•

On October 13, 2016, Energia São Paulo Fundo de Investimento em Ações, an investment fund (fundo de investimento em ações fechado) organized under the laws of the Federative Republic of Brazil (the “Bonaire Investor”) and each of the shareholders of the Bonaire Investor, (i) Fundação CESP, (ii) SISTEL - Fundação Sistel de Seguridade Social, (iii) Fundação Petrobras de Seguridade Social – PETROS and (iv) Fundação SABESP de Seguridade Social — SABESPREV (each of the entities referred to in (i) through (iv) being a closed complementary pension fund (entidade fechada de previdência complementar) organized under the laws of the Federative Republic of Brazil and referred to herein collectively as the “Bonaire Shareholders” and together with the Bonaire Investor, as the “Bonaire Sellers”), perfected the exercise of certain tag-along rights available to them pursuant to the Issuer Shareholders Agreement in connection with the execution by Camargo and ESC of the Original SPA by executing and delivering to State Grid Brazil a Seller Accession Agreement (the “Bonaire Accession Agreement”) pursuant to which the Bonaire Sellers each became a party to the Original SPA in the position of a “Seller” and each agreed to sell to State Grid Brazil all of the Seller Shares (as defined below) owned by it (the Original SPA, as supplemented and modified by the PREVI Accession Agreement, the Bonaire Accession Agreement and the Indirect Sale Notice and Accession Agreement, being the “Amended SPA”). On November 11, 2016, the Bonaire Investor ceased to be a “Seller” pursuant to the Original SPA following the transfer of the Seller Shares owned by it to the Bonaire Shareholders.

•

The Closing occurred on January 23, 2017. At the Closing, the Reporting Persons (acting through State Grid Brazil) acquired (i) all of the Common Shares directly or indirectly owned by Camargo, PREVI and the Bonaire Shareholders that were bound by the Issuer Shareholders Agreement plus (ii) all dividends of Common Shares (bonificação em ações) received thereon (or resulting from stock splits thereof) on or after January 1, 2016 and prior to January 23, 2017 ((i) and (ii) collectively, the “Seller Shares”), which constituted 556,164,817 Common Shares in the aggregate. As contemplated by the Amended SPA, in connection with the Closing, Martin Roberto Glogowsky, Carlos Alberto Cardoso Moreira, Danilo Ferreira da Silva, Luiza Damasio Ribeiro do Rosário, Murilo Passos, Francisco Caprino, José Florêncio Rodrigues, Fernando Aguiar, Roberto Evangelista, Lívio Kuze, Adalgiso Faria, Marcelo Andrade, Paulo Ionescu, Susana Silveira, Décio Bottechia Júnior, Arnaldo José Vollet, Fernando Manuel Pereira Afonso Ribeiro, Heloísa Helena Silva de Oliveira, William Bezerra Cavalcanti Filho, João Pinto Rabelo Junior, Benilton Couto da Cunha and Noel Dorival Giacomitti resigned from their positions as directors, alternate directors and fiscal board members (in each case as applicable) of the Issuer and are expected to be replaced by the following State Grid Brazil nominees: Yuhai Hu, Daobiao Chen, Yang Qu, Yumeng Zhao, Andre Dorf, Antonio Kandir, Yuehui Pan, Chenggang Liu, Ran Zhang, Jia Jia, Luiz Augusto Marques Paes and Reginaldo Ferreira Alexandre.

•

Also at the Closing on January 23, 2017, ESC, PREVI and the Bonaire Shareholders entered into a deed of termination with the Issuer terminating the Issuer Shareholder’s Agreement (the “SHA Termination Agreement”).

The Reporting Persons view their investment in the Issuer as a strategic opportunity, the principal purpose of which is to diversify their business portfolio and take advantage of synergies between the Issuer and existing transmission assets of the Reporting Persons, and to thereby strengthen their position in the Brazilian power sector. The Reporting Persons intend to exercise control over the Issuer’s business and operations.

As required by Brazilian law, the Reporting Persons currently expect to commence the Tender Offer and the Subsidiary Tender Offer following completion of applicable Brazilian registration requirements. The Reporting Persons currently expect that such Brazilian registration process will commence on or prior to February 22, 2017. The Reporting Persons may, in connection with the Tender Offer, seek to cause the Issuer to delist from the NYSE and to cause the Issuer to deregister as a public company in the United States. Though no final decision has yet been made, the Reporting Persons are also currently considering whether they will cause the Issuer and/or CPFL Energias Renováveis S.A. to deregister as category A issuers in Brazil within one year of January 23, 2017. The Reporting Persons may, subject to applicable law, purchase, or enter into arrangements to purchase, (i) Common Shares and/or ADRs prior to or during the pendency of or after the Tender Offer and (ii) securities of CPFL Energias Renováveis S.A. prior to or during the pendency of or after the Subsidiary Tender Offer.

In addition to the foregoing, the Reporting Persons intend to enter into discussions from time to time with members of the Issuer’s management, fiscal board and/or board of directors and/or with other shareholders of the Issuer and/or other third parties in connection with their acquisition of control over the Issuer. Such discussions may include, without limitation, discussions with respect to the governance, board composition, management, operations, business, assets, capitalization, financial condition, strategic plans and future of the Issuer, as well as other matters related to the Issuer. These discussions may also include a review of options for enhancing shareholder value through, among other things, various strategic alternatives (including acquisitions and divestitures) or operational or management initiatives. The Reporting Persons intend to review their investment in the Issuer on a continuing basis and may take from time to time and at any time in the future, depending on various factors (including, without limitation, the outcome of any discussions referenced above), such actions as they deem appropriate in respect thereof, including proposing or considering, or changing their intention with respect to, one or more of the actions described above or otherwise referred to in subparagraphs (a)-(j), inclusive, of Item 4 of Schedule 13D.

The foregoing description of the Original SPA, the Indirect Sale Notice and Accession Agreement, the PREVI Accession Agreement, the Bonaire Accession Agreement and the SHA Termination Agreement (collectively, the “Principal Transaction Documents”) is not, and does not purport to be, complete and is qualified in its entirety by reference to the copies of the Principal Transaction Documents filed herewith as Exhibits 2, 3, 4, 5 and 6 respectively, all of which are incorporated into this Item 4 by reference.

Item 5.

The responses of the Reporting Persons to rows (7) through (13) of the cover pages and Items 2, 3, 4 and 6 of this Schedule 13D are incorporated into this Item 5 by reference. The Reporting Persons are in the aggregate beneficial owners of 556,164,817 Common Shares (or approximately 54.6% of the 1,017,914,746 Common Shares stated by the Issuer in the Form 6-K to be outstanding as of September 30, 2016) and all of the Reporting Persons have shared power to vote or direct the vote of, and shared power to dispose of or direct the disposition of, all of such Common Shares.

To the Reporting Persons’ knowledge, none of the Covered Persons directly owns any Common Shares; however, because each Covered Person is a director or executive officer of one or more Reporting Persons, each Covered Person may be deemed to be the beneficial owner of the Common Shares beneficially owned by the Reporting Person(s) for which they each serve as director or executive officer. Each of the Covered Persons hereby disclaims beneficial ownership of any Common Shares and the filing of this Schedule 13D shall not be construed as an admission that any such Covered Person is the beneficial owner of any securities covered by this Schedule 13D or that any such Covered Person is a member of a “group” for Section 13(d) purposes.

(c)

Except for the transactions described in Item 3, Item 4 and Item 6 of this Schedule 13D, which are incorporated into this Item 5(c) by reference, none of the Reporting Persons nor, to their knowledge, any of the Covered Persons, has effected any transactions in Common Shares during the past 60 days.

(d)	Except as disclosed in this Schedule 13D, no other person is known to the Reporting Persons to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Common Shares covered by this statement on Schedule 13D.

(e)	Not applicable.

Item 6.

The Indemnifying Party shall have thirty (30) days (or such lesser number of days set forth in the Claim Notice as may be required by a court proceeding in the event of a litigated matter) after receipt of the Claim Notice (the “Notice Period”) to notify the Indemnified Party that it desires to defend the Indemnified Party against such Third Party Claim it being understood that by assuming the defense of a Third Party Claim the Indemnifying Party shall be deemed to have irrevocably acknowledged that it has an indemnification obligation hereunder with respect to such Third Party Claim.

(b) In the event that the Indemnifying Party notifies the Indemnified Party within the Notice Period that it desires to defend the Indemnified Party against a Third Party Claim, the Indemnifying Party shall have the right to defend the Indemnified Party by appropriate proceedings and shall have the sole power to direct and control such defense, with counsel reasonably satisfactory to the Indemnified Party, at the Indemnifying Party’s expense. Once the Indemnifying Party has duly assumed the defense of a Third Party Claim, the Indemnified Party shall have the right, but not the obligation, to participate in any such defense, and to employ separate counsel of its choosing, at its own expense. The Indemnifying Party shall not, without the prior written consent of the Indemnified Party, settle, compromise or offer to settle or compromise any Third Party Claim on a basis that would result in (i) the imposition of a consent order, injunction or decree that would restrict the future activity or conduct of the Company or

-57-

any Company Subsidiary or of the Indemnified Party or any of its Affiliates, (ii) a finding or admission of a violation in respect of a Covered Law or that could reasonably be expected to result in material adverse reputational harm to the Indemnified Party, any of its Affiliates, the Company or any Company Subsidiary, or (iii) any non-monetary condition or obligation being imposed on the Company or any Company Subsidiary or on the Indemnified Party or any of its Affiliates.

(c) If the Indemnifying Party (i) elects not to defend the Indemnified Party against a Third Party Claim, whether by not giving the Indemnified Party timely notice of its desire to so defend or otherwise or (ii) after assuming the defense of a Third Party Claim, fails to take reasonable steps necessary to defend diligently such Third Party Claim, the Indemnified Party shall have the right but not the obligation to assume its own defense, it being understood that (x) the Indemnified Party’s right to indemnification for a Third Party Claim shall not be adversely affected by assuming the defense of such Third Party Claim and (y) if the Indemnifying Party so requests (and has not disclaimed its indemnification obligation hereunder with respect to such claim) the Indemnified Party shall keep the Indemnifying Party reasonably apprised of the status of such Third Party Claim.

(d) The Indemnified Party and the Indemnifying Party shall reasonably cooperate in order to ensure the proper and adequate defense of a Third Party Claim, it being understood that the costs and expenses of the Indemnified Party relating thereto shall be considered Losses. The Indemnified Party and the Indemnifying Party shall keep each other fully informed with respect to the status of such Third Party Claim.

(e) The Indemnified Party and the Indemnifying Party shall use reasonable best efforts to avoid production of confidential information (consistent with Law), and to cause all communications among employees, counsel and others representing any party to a Third Party Claim to be made so as to preserve any applicable attorney-client or work-product privileges.

Section 9.5 Direct Claims. If an Indemnified Party wishes to make a claim for indemnification hereunder for a Loss that does not result from a Third Party Claim (a “Direct Claim”), the Indemnified Party shall notify the Indemnifying Party in writing of such Direct Claim and the amount or the estimated amount of damages sought thereunder to the extent then ascertainable (which estimate shall not be conclusive of the final amount of such Direct Claim). The Indemnifying Party shall have a period of sixty (60) days within which to respond to such Direct Claim. If the Indemnifying Party does not respond within such sixty (60) day period, the Indemnifying Party will be deemed to have irrevocably acknowledged its obligation to indemnify, defend and hold harmless the Indemnified Parties in respect of Direct Claim. If the Indemnifying Party rejects all or any part of the Direct Claim, the Indemnified Party shall be free to seek enforcement of its rights to indemnification under this Agreement with respect to such Direct Claim.

Section 9.6 Limitations on Indemnification. Subject to this Section 9.6, no Seller shall be required to indemnify any of the Buyer Indemnified Parties for any Losses pursuant to Section 9.2(a) (i) with respect to any claim unless such claim (or series of related or similar claims) involves Losses in excess of R$1,000,000 (taking into account the entire amount of such Loss otherwise indemnifiable by any other Seller hereunder), (ii) until the aggregate amount of the Losses to which the Buyer’s Indemnified Parties would otherwise be entitled to indemnification pursuant to Section 9.2(a) exceeds 0.75% of the aggregate of all Seller Purchase Price Amounts actually paid by Buyer at all Closings having actually occurred (taking into account the entire amount of all Losses otherwise indemnifiable by any other Seller hereunder) (such amount, the “Basket”), after which the Sellers shall be liable to the Buyer Indemnified Parties hereunder for all such Losses from the first Reais of Loss (including, for the avoidance of doubt, the Losses included in the Basket) or (iii) in a cumulative aggregate amount exceeding, with respect to each Seller (and not taking into account any Losses indemnified or indemnifiable by any other Seller hereunder), 7.5% of such Seller’s Seller Purchase Price Amount; provided that to the extent any Loss arises as a result of or in connection with the breach of any Seller Fundamental Warranty or any HoldCo Fundamental Warranty, clause (ii) above shall not apply and clause (iii) above shall be deemed (solely as it applies to Seller Fundamental Warranties (other than Capped Fundamental R&Ws) and HoldCo Fundamental Warranties) to include the words “100.0%” in lieu of “7.5%” therein. To the extent a Buyer Indemnified Party suffers a Loss arising out of, resulting from, based upon, with respect to or by reason of a breach of or an inaccuracy in a representation or warranty in Article IV made by the Sellers with respect to the Company or a Subsidiary of the Company, each Seller shall only be required to indemnify the applicable Buyer Indemnified Party for such Seller’s Modified Pro Rata Share of such Loss (without prejudice to (i) such Buyer Indemnified Party’s right to seek indemnification for the remainder of such Loss from the other Sellers or (ii) the obligations of such other Sellers to indemnify such Buyer Indemnified Party for such remaining amount); provided that, without duplication, Section 9.7, and not this sentence of Section 9.6, shall apply to the extent any Loss is suffered directly by the Company or a Company Subsidiary, and not directly by a Buyer Indemnified Party. Nothing in this Agreement shall have the effect of limiting in any way a Party’s remedies for claims brought on the basis of fraud (fraude), willful misconduct (ma-fé) or malice (dolo, whether relating to an action or an omission). The Parties acknowledge that Losses of a Buyer Indemnified Party or Seller Indemnified Party shall not include punitive, incidental (other than fees, costs or expenses related to litigation) or indirect damages (including loss of profits), except to the extent that they relate to Losses resulting from a Third Party Claim or to any Loss that would not have arisen if Buyer had purchased the Shares held by ESC directly rather than indirectly through an Indirect Sale.

Section 9.7 Company Losses. Notwithstanding the last sentence of Section 9.6, to the extent the Company or any Company Subsidiary suffers a Loss pursuant to which it would have been entitled to indemnification hereunder had it been a Buyer Indemnified Party, such amount shall be deemed a direct Loss of Buyer subject to

-59-

indemnification directly to Buyer by each Seller hereunder according to such Seller’s Pro Rata Share.

Section 9.8 Remedies. The Parties expressly agree that, (as between Buyer and each Seller) following the Closing between Buyer and such Seller, their sole and exclusive monetary remedy for the events set forth in this Article IX shall be the indemnification provisions of this Article IX.

Section 9.9 Investigation by Buyer. The right of a Person to any remedy pursuant to this Article IX shall not be affected by any investigation or examination conducted, or any knowledge possessed or acquired (or capable of being possessed or acquired), by such Person at any time concerning any circumstance, action, omission or event relating to the accuracy or performance of any representation, warranty, covenant or obligation.

Section 9.10 Additional Agreements. The Parties agree to the matters set forth in Schedule 9.10.

Section 13.10 Arbitration.

(a) Any discrepancy, dispute, controversy or claim arising out of or relating to this Agreement, including, but not limited to, the existence, validity, effectiveness, interpretation, performance, implementation, termination or any breach hereof or thereof (a “Dispute”) among the Parties, including any of its successors at any title, shall be exclusively and definitively resolved, without any recourse to appeal, by final and binding arbitration. The seat of such arbitration shall be, and the arbitration hearings shall be held in, the City of São Paulo, State of São Paulo, Brazil. The arbitration shall be administered by the International Court of Arbitration of the International Chamber of Commerce (“ICC”) in accordance with the Rules of Arbitration of the ICC (“Arbitration Rules”), as in effect as of the date of commencement of the

-66-

arbitration, as modified by this Agreement or mutual agreement of the Parties, and with Law 9,307/96.

(b) The arbitration shall be conducted in the English language, although documents or testimony may be submitted in Portuguese or any other languages if a translation is provided.

(c) The arbitration panel shall be composed of three arbitrators. The first arbitrator shall be appointed by the claimant. The second arbitrator shall be appointed by the respondent. The third arbitrator (who shall act as chairman) shall be appointed by the two party-appointed arbitrators, within fifteen (15) days from the date of confirmation of the second party-appointed arbitrator. If any Party fails to appoint an arbitrator within the required period, or if the two arbitrators cannot reach an agreement with respect to the third arbitrator within the applicable periods, the appointment shall be made by the ICC International Court of Arbitration pursuant to the Arbitration Rules. To the extent that a Dispute involves more than one party as claimant, such claimants shall jointly appoint the first arbitrator. To the extent that any Dispute involves more than one respondent, such respondents shall jointly appoint the second arbitrator.

(d) In case of an arbitration involving three (3) or more parties that can neither be set in a group of claimants nor in a group of respondents, the parties, in agreement, shall appoint two arbitrators within fifteen (15) days after receipt of the last notice by the ICC in this sense. The third arbitrator, whom shall act as the President of the arbitration panel, shall be appointed by the party-appointed arbitrators within fifteen (15) days after the confirmation of the last arbitrator or, if that is not possible by any reason, by the ICC, in accordance with the Arbitration Rules. If the parties fail to appoint the arbitrators, all members of the arbitration panel shall be appointed by the ICC, in accordance with the Arbitration Rules, which shall designate one of them to serve as chairman of the arbitration panel.

(e) Provided that the terms of reference have not been signed by the parties or approved by the ICC, the ICC may consolidate two or more simultaneous arbitral proceedings arising out of this Agreement or any other agreement entered by the Parties, as the case may be, in accordance with the Arbitration Rules. After the terms of reference are signed by the parties of the Dispute or it is approved by the ICC, the arbitration panel may consolidate arbitral proceedings based on this or any other agreement provided that: (i) the arbitral proceedings arise in connection with the same legal relationship; (ii) the arbitration clauses are compatible; (iii) no party would be unduly prejudiced; and (iv) consolidation under these circumstances would not result in undue delay. The arbitration panel that was first constituted shall have jurisdiction for consolidation and its decision shall be final and binding upon the parties to all proceedings.

(f) Any award of the arbitration panel must be in writing and state the grounds upon which it is based. The award shall be final and binding on the Parties and

-67-

their successors at any title, and a judgment upon the award may be recognized and enforced in any court of competent jurisdiction. The fees of the arbitration and other reasonable and documented costs of the party which has prevailed in such arbitration, including reasonable attorney’s fees, shall be borne as established by the arbitration panel.

(g) As soon as constituted, the arbitration panel may, at the request of a Party, order any interim or conservatory measure it deems appropriate. The arbitration panel may make the granting of any such measure subject to appropriate security being furnished by the requesting party. Any such measure shall take the form of an order, giving reasons, or of a partial award, as the arbitration panel considers appropriate. Before the constitution of the arbitration panel, the Parties may apply to any competent judicial authority or to the Emergency Arbitrator, as provided in the Arbitration Rules, for interim or conservatory measures. The application of a Party to a judicial authority or to the Emergency Arbitrator for such measures or for the implementation of any such measures ordered by the arbitration panel shall not be deemed to be an infringement or a waiver of the arbitration agreement and shall not affect the relevant powers reserved to the arbitration panel.

(h) Each Party’s promise to resolve all Disputes as set forth herein is given in consideration for the other Party’s like promise. The details or existence of any Disputes, any formal or informal meetings and proceedings conducted hereunder, and any discovery taken in connection with any arbitration, shall be kept strictly confidential and shall not be disclosed or discussed with any third party (excluding a Party’s attorneys, accountants, insurers and other agents and representatives, as reasonably required in connection with any Dispute resolution procedure hereunder), except as otherwise required by any Law or rule of any securities exchange on which such Party’s securities are traded, and as necessary in court proceedings in relation to the arbitration or to enforce or set aside the arbitration award.

(i) Each Party retains the right to seek judicial assistance to: (a) enforce the applicability of the arbitration; (b) obtain interim measures of protection and (c) enforce any decision of the arbitrators, including the final award. All interim and urgent measures, when applicable, and enforcement procedures, shall be requested to any court having jurisdiction over the Parties, as the case may be, their assets or to the courts of the city of São Paulo, State of São Paulo, Brazil. For any other judicial measures, the Parties hereby elect, the courts of the City of São Paulo, State of São Paulo shall have jurisdiction on such matters.

Section 13.11 Cumulation of Remedies. Subject to the specific limitations set out in this Agreement, no remedy conferred by any provision of this Agreement is intended to be exclusive of any other remedy except as expressly provided for in this Agreement, and each and every remedy shall be cumulative and shall be in addition to every other remedy given thereunder or existing at law by statute or otherwise.

Each Party acknowledges and agrees that the Parties would be damaged irreparably in the event any provision of this Agreement is not performed in accordance with its specific terms or is otherwise breached, so that, in addition to any other remedy that a Party may have under law or equity, each Party shall be entitled to injunctive relief to prevent breaches of the provisions of this Agreement and to enforce specifically this Agreement and the terms and provisions hereof, including the Closing.

Exhibit 3

Indirect Sale Notice and Accession Agreement

This INDIRECT SALE OPTION NOTICE AND ACCESSION AGREEMENT, dated as of October 3^rd, 2016 (this “Agreement”), is being entered into by Camargo Correa S.A. (“CCSA”) (in its existing capacity under the Share Purchase Agreement (as defined below) and additionally in its capacity as a HoldCo Seller) and VBC Energia S.A. (a “HoldCo Seller” and together with CCSA, the “HoldCo Sellers”) and ESC Energia S.A. (the “ESC”) with respect to the Share Purchase Agreement, dated as of September 2nd, 2016 (the “Share Purchase Agreement”), by and among State Grid Brazil Power Participações Ltda, State Grid International Development Limited, ESC Energia S.A., Camargo Corrêa S.A. and any other Seller becoming a party to the Share Purchase Agreement in accordance with Article X thereof. Capitalized terms not otherwise defined herein shall have their respective meanings set forth in the Share Purchase Agreement.

WHEREAS, ESC and CCSA desire to effect an Indirect Sale pursuant to Section 2.9 of the Share Purchase Agreement;

WHEREAS, in furtherance thereof, each of the HoldCo Sellers desires to accede to the Share Purchase Agreement as a Party in the position of a “HoldCo Seller” as provided herein and in the Share Purchase Agreement and, in connection therewith, to make the representations warranties, covenants and agreements contained herein,

NOW, THEREFORE, in consideration of the foregoing and the representations, warranties, covenants, agreements and conditions set forth in this Agreement and in the Share Purchase Agreement, and intending to be legally bound hereby, the parties hereby agree, for the benefit of the other parties hereto and of each other Party to the Share Purchase Agreement, as follows:

1. Notice of Indirect Sale Election. Each of the HoldCo Sellers, ESC and CCSA hereby certifies to Buyer that each of the Hold Co Conditions has been and remains satisfied as of the execution hereof, and ESC and CCSA hereby deliver notice to Buyer that they are irrevocably electing to effect an Indirect Sale pursuant to Section 2.9 of the Share Purchase Agreement, subject to the satisfaction or waiver at the Closing of the conditions precedent thereto set forth in Article VII to the Share Purchase Agreement and provided that the HoldCo Conditions at all times remain satisfied.

2. Accession to Share Purchase Agreement. The HoldCo Sellers and each other party hereto hereby agrees that, by executing and delivering this Agreement to Buyer, each HoldCo Seller has, subject to Section 2.9 of the Share Purchase Agreement, become a party to the Share Purchase Agreement in the position of a “HoldCo Seller”(with all attendant rights, duties and obligations stated in the Share Purchase Agreement as being applicable to HoldCo Sellers, with the same force and effect as if such HoldCo Seller had executed the Share Purchase Agreement on the date thereof as a HoldCo Seller). Each of the HoldCo Sellers and each other party hereto hereby waives any and all claims, defenses or other rights it might otherwise be able to assert that it has not effectively become a party to the Share Purchase Agreement in the position of a “HoldCo Seller”, without prejudice to Buyer’s right to assert the same or to waive any non-compliance by either HoldCo Seller with respect to the conditions to accession. The

accession to this Agreement by CCSA as a “HoldCo Seller” is in addition to and not in substitution of, and is without prejudice to, the other rights, duties and obligations of Camargo Corrêa S.A. pursuant to the Share Purchase Agreement, including in its capacity as a “Seller” in respect of the Dividend Shares and with respect to the guarantee provided by it pursuant to Article XI of the Share Purchase Agreement.

The copy of the bylaws of such HoldCo Seller furnished by such Seller to Buyer (with respect to ESC and CCSA) prior to the date hereof, or (with respect to each Seller other than ESC and CCSA) prior to the date it became a Party to this Agreement, reflects all amendments made thereto and is correct and complete in all respects. All of the HoldCo Conditions are satisfied. VBC Energia S.A. is 100% directly or indirectly owned by CCSA.
